whizzer71 0 Posted April 27, 2008 (edited) As per ttle what cam did turbo technics use in the original 205 1.9 Turbos ?,was it the std 1.9 Gti item or was it a one off specifically for their conversion ? Edited April 27, 2008 by whizzer71 Share this post Link to post Share on other sites
whizzer71 0 Posted April 27, 2008 What pistons did they use and are they still available ?,Im still toying with the idea of Turboing the std 1.9 engine thats currently in my 205 as only has 52K on it with FSH,Car is so nimble with the alloy engine in it and after having two others with cast lumps I deffo notice the difference !

tom_m 0 Posted April 27, 2008 std pistons machined to drop the CR Share this post Link to post Share on other sites
whizzer71 0 Posted April 27, 2008 Dont spose you know how much by do you Tom ?,You sound like you know a bit about these engines...also where did the oil return from the turbo drain back to / fit in to ? Share this post Link to post Share on other sites
danpug 1 Posted April 27, 2008 Oil drain was back into sump. Iirc the compression was 8.6:1 or 8.7:1. Share this post Link to post Share on other sites
tom_m 0 Posted April 27, 2008 no idea i'm afraid, but i know they'll still machine the pistons for you if you send them to them and i believe the oil return was welded into the sump, but don't quote me on that. Share this post Link to post Share on other sites

Miles 331 1 Cars Posted April 27, 2008 You can run them at std compression and get good results with a decent ECU fitted and not this 5th Injector rubbish Share this post Link to post Share on other sites
Bally 4 Posted April 28, 2008 We have been getting real good results recently with High compression turbo, using water/methanol injection. Share this post Link to post Share on other sites
whizzer71 0 Posted April 28, 2008 You can run them at std compression and get good results with a decent ECU fitted and not this 5th Injector rubbish Prob wont be able to run much boost then ?,What sort of power could I expect to see from a standard D6B engine in good condidtion (52K) + turbo and mappable injection,I would rather strip it down and get pistons machined if it meant I could run more boost and get more torque/power. Or could I just fit XU10 2.0 ltr 8 V turbo head with no machining of the pistons to get the compression sufficiently low ? Sorry about all the Q's just wondering what my options are,I know the alloy engine isnt as strong as the cast unit but as I said earlier the cars feel so nimble with the lighter engine Share this post Link to post Share on other sites
Batfink 201 Posted April 28, 2008 with modern ecu's the fuelling is infinitely more controllable so this idea of low compression to turbo is somewhat a red herring. I'm sure it was Miles who told me to look at the Subaru rally cars. They run higher compression than the road cars. A bit extreme but its food for thought.

welshpug 1,626 Posted April 28, 2008 (edited) VAG run their injection a step further advanced with Direct injection, but they still run 11-1 with boost on the 2.0T in the Mk5 Glof GTi, not sure what ratio they run in the S3 though. as Miles and Batfink say its all down to the control and mapping of the fuelling and spark. edit, M5 golf gti runs 0.9 bar of boost for 200 hp and 280Nm, S3 runs 9.8-1 with 1.2 bar for 265ps and 350 Nm Edited April 28, 2008 by welshpug Share this post Link to post Share on other sites
Batfink 201 Posted April 28, 2008 yes but the engine in a wrc car only has to last 2 rallys not being driven day in day out. Like i said...its an extreme example, but my point still stands. Fueling has come a long way. There are loads of examples of turboed cars which put out far more power than ever before due to more finesse with regards to fuelling control and intake temperatures Share this post Link to post Share on other sites

Goliath 94 Posted April 28, 2008 sorry to be a dumbass but when you say mappable ecu do you mean one like the ones sold by emerald? cheers Share this post Link to post Share on other sites
